I have never seen some one in india to go this deep into repairing the board. , Forget oscilloscope, most repair techs do not even have basic tools like clamp meter or vaccum pump. Very very impressed with your work here. Also liked the use of ppe. I have 5 panasonic, 2lg , 1hitachi 2 whirlpool. So every year i am fixing one or another ac in my home , i have done board level repairs on Panasonic like replacing the psu ic. Or steeper motor driver. But i would have not been able to identify this optocoupler fault as i do not have a scope.
